(1) Prepare an HTML file, prob3.html, with the following content:

 This program computes 1 + 2 + 3 + .... + n where n is entered from the browser. 
 
 Enter n: 
  
  

where your_account_name needs to be replaced by your actual login name. Verify boxes and other tags.(2) Write a CGI program which communicates with the above program to return the desired result.(3) Execute

Note: You have to place this *.html file in the public_html directory, not in the cgi-bin directory.Hint The following html file and c (cgi) file compute the sum of two numbers entered from the browser:

 This program computes the sum of two numbers. 
 
 Enter m: 
 Enter n: 
  
  

#include  #include  int main() { float m,n; /* The variable input takes parameters passed by HTML */ char *input = getenv("QUERY_STRING"); /* We now separate m and n from one long string of "input" */ sscanf(input, "number1=%f&number2=%f", &m, &n); /* CGI script must spit the following string no matter what ! */ printf("Content-type: text/html "); /* Any printf command hereafter is output to the web browser. */ printf("The sum is = %f" ,m+n); return 0; }
